Rachel Armstrong is talking about the future of architecture
She likes architecture because of its scale - it's the biggest things we make. And it's the footprint we leave behind. Architecture has always been a technology. The materials we chose in architecture have been there to wall out nature. This creates belligerent architectures that oppose nature.
Buildings are 40% of our carbon footprint, and are still largely built using Victorian techniques. Sustainable architectures needs to be connected to the natural world. Living systems are in constant conversation with the rest of the world through the chemical processes of metabolisms. Imagine if the surfaces of our buildings have metabolic functions - how much difference could that make to the environment?
Low tech biotech: different from most biotech, which is expensive technology created in sterile laboratories. We don't know what all bacteria in urban landscapes actually do - which of them are actually beneficial? Could bioluminescent bacteria be used to light parts of the cities?
